Product Analysis: Pfannenberg PF 11.000 Filterfan (230V)
The 11611801055 is a compact and efficient PF 11.000 Series Filterfan from Pfannenberg’s 4th Generation family. Designed for 230V AC operation, this unit is the premier solution for the cooling of small-to-medium electrical enclosures. It prevents thermal derating of PLCs, power supplies, and other internal components by providing a continuous flow of filtered cool air into the cabinet. Its ultra-slim design makes it ideal for side-wall or door mounting in high-density automation panels.
High Performance in a Compact Frame
The PF 11.000 features a flow-optimized fin design that maximizes air displacement while minimizing electrical noise and power consumption. The 11611801055 model utilizes high-grade ball bearings to ensure a long service life of up to 40,000 hours. With an unimpeded airflow of 25 m³/h, it provides the necessary thermal regulation for systems where space is at a premium but reliability is paramount.
